I have bought a PSP 3000 v5.50 for my son recently from Walmart. After days of research I made the leap and installed 6.35 pro-b on the PSP and 5 minutes later it works as advertised. I will post the link to the website I used and provide a short walk through for those of you who wish to 'hack' your PSP. This also works for PSPGO and PSP2000 (certain models).

1. I upgraded my PSP's version from 5.50 to 6.35. There are multiple sites providing the link to upgrade your version, please make sure you use a credible site. I used MEGAUPLOAD - The leading online storage and file delivery service.

2. Then I installed Virtuous Flame’s CFW 6.35 Pro-B. I used PSP Downloads | PSP Custom Firmware 6.35 PRO-B. Within that compressed package are two files, put them in your I:\PSP\GAME\ directory where I:\ is your PSP's memory card (to access this you must plug in your PSP to your computer and turn on USB connect through your menu).

3. Once those files have been copied over, you may safely disconnect your PSP and through the menu go to 'games' and scroll to the bottom where you can select your memory card. Within there you must run 635 PRO update to install the 'hack'.

4. Now you're almost ready to go, the other selection within your memory card on your PSP should be a 'fast recovery'. This must be loaded every time you hard boot your PSP (if you just put it into sleep mode you're good), takes about 15-20 seconds, screen will go black then back to the main menu. And BAM, you're ready to play your ISO games or movies.

5. ISO games should be put into I:\ISO\
6. Movies are put into I:\MOVIES
7. and music into I:\MUSIC
